A new study sheds light on the action of the drug ezetimibe (trade name Zetia), which is used to treat high cholesterol. Ezetimibe is unique among cholesterol-lowering drugs in that it works by cutting the amount of cholesterol taken in from the diet rather than by blocking cholesterol's manufacture in the body.

Teenagers who excessively use their cell phone are more prone to disrupted sleep, restlessness, stress and fatigue. When compared to subjects with restricted use of cell phones, young people with excessive use of cell phones (both talking and text messaging) have increased restlessness with more careless lifestyles, more consumption of stimulating beverages, difficulty in falling asleep and disrupted sleep, and more susceptibility to stress and fatigue. They behave more like larks than owls, suggesting a delayed biological clock. Source: ScienceDaily: Latest Science News | 9 Jun 2008 | 9:00 pm
Like a wristwatch that needs to be wound daily for accurate time-telling, the human circadian system -- the biological cycles that repeat approximately every 24 hours -- requires daily light exposure to the eye's retina to remain synchronized with the solar day. Researchers have demonstrated that when it comes to the circadian system, not all light exposure is created equal. Source: ScienceDaily: Latest Science News | 9 Jun 2008 | 9:00 pm
Scientists working at NASA's Goddard Space Flight Center have concocted an innovative recipe for giant telescope mirrors on the Moon. To make a mirror that dwarfs anything on Earth, just take a little bit of carbon, throw in some epoxy, and add lots of lunar dust. Source: ScienceDaily: Latest Science News | 9 Jun 2008 | 9:00 pm

When Sammie Bush mentioned to his doctor that he sometimes felt something in the back of his throat, he didn't expect to learn that he had cancer or that he would be the first patient at the University of Illinois Medical Center at Chicago to undergo photodynamic therapy -- a new procedure that uses light to destroy cancer.

The road to death or differentiation follows a similar course in embryonic stem cells according to new research in the journal Cell Stem Cell. Caspases, known as 'killer enzymes,' that are activated during programmed cell death, are also active in the initial phases of cell differentiation, according to researchers.

One of the great scientific challenges is to understand the design principles and origins of the human brain. New research has shed light on the evolutionary origins of the brain and how it evolved into the remarkably complex structure found in humans. The research suggests that it is not size alone that gives more brain power, but that, during evolution, increasingly sophisticated molecular processing of nerve impulses allowed development of animals with more complex behaviors.

Heat waves, droughts and fuel prices are just a few reasons for the current global food crisis that is making headlines around the world. New research indicates that rising background levels of ozone in the atmosphere are a likely contributor to the problem, lowering the yield of important food crops, such as wheat and soybeans.

Maternal diet influences the chances of having male or female offspring. New research in Reproductive Biology and Endocrinology has demonstrated that ewes fed a diet enriched with polyunsaturated fats for one month prior to conception have a significantly higher chance of giving birth to male offspring.

LiveScience.com - They may "speak" different languages, but Asian and European honeybees living in the same hive can learn to translate each others' dances to help one another find food, a new study reveals.
Honeybees produce and store honey and build colonial hives from wax. The nine species of honeybees found worldwide diverged, in evolutionary terms, about 30 million to 50 million years ago and developed different dance "languages" that they use to tell each other where a tasty flower or choice nesting site is. ...
